IMPROVEMENT lN VELOCIPEDES.

Specification forming part of Letters Patent No. 217,535, dated July 15,1879; application filed March 22, 1879.

To all whom it may concern:

Be it known that I, RoswELL R. INGER- SOLL, of Brooklyn, county ofKings, State of New York, have invented a new and useful Improvement inMotions for Velocipedes and I do hereby declare/that the following is aclear and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification.

The object of my invention is to produce a cheap, simple, and effectivemechanical device for revolving the wheels of a velocipede or any othermachine operated by hand, foot, or otherwise, such as a sewing-machine.

To assist me in the description of my invention I will turn at once tothe drawings, of which- Figure I is a side view of a velocipedeembodying my invention. Fig.'II is a plan View of the same. Fig. III isan enlarged sectional view on line as as, Fig. I. Fig. IV is a sectionalview on line y 3 Fig. II. Fig. V is a detached face view of the hub.Fig. VI is a detached face View of the cam-plate, andv Fig. VII is adetached end view of the hub.

A A are two axles, supported and revolving in a journal-box. attached tothe horizontal support-piece C. The outer ends of these axles areprovided with wheels D D.

E E are two disks, fastened onto the axles A A at a a, which disks areprovided with annular grooves e 0. Against these disks are placed thecamplates F F, which are provided with outward-projecting lugs f f f f.The lugs ff enter the annular grooves e e, and the lugs f f project overthe top of the disks E E, which are provided with serrated innersurfaces.

The plates F F are provided with a hole, f", in the center, andupward-projecting lugs f f 1 Against the plates F F are placed the hubsG G, which are permitted to revolve loosely around the axlesAA. Theouter faces of the hubs Gr Gr are provided with metal boxes or bearingsg g, which have circular lugs g g, projecting out therefrom. These lugsenter the holes f f in the plates F F,

and are provided with slots g g, into which enter the lugs f fThe-object of this arrangement is to cause the hub to take hold upon thecam-plate F in order to turn it. To further cause the hub to turn theplate, I use a pin, j, which rests against a spring-plate, g fastened tothe hub G. (See Fig. V.)

' H H are two levers, with handles it h, which levers are fulcrumed at kh t3 the arms W 71. projecting from the arch-frame I, fastened to theaxles at z i. The lower ends of these levers are connected to the hubs GG by the straps h k which are connected at one end to the levers and atthe other ends to the hubs after passing once around the same, as shown.

By drawing the levers inward the hubs G G are made to revolve, and thehubs in turn rotate the cam-plates F F. As the plates revolve, theserrated lugs f f are pressed down upon the disks E E, causing them alsoto revolve and to carry with them the axle and wheels. After the hubsare revolved forward as far as the straps will allow they areautomatically revolved back to their relative positions by the springs JJ, and are again ready to be revolved by the levers, as hereinbeforedescribed. K is a seat, and L a steering apparatus.

Having thus described my invention, I desire to claim The combination ofthe axles A, the hubs G, having the metal boxes g and circular lugs 9which latter are provided with the slots g and the spring-plate g andpin f, the camplates F, provided with open center f and lug f on oneside, and circular projections or lugs ff on the other, the disks E,having grooves e, and the'lever H, the lever and hub being connected bymeans of the straps h and spring J, all constructed and operating asdescribed.

This specification signed this 5th day of March, 1879.
